I'm trying to load an image into my profile and clicking the edit button does nothing.
I have successfully loaded both a shop avatar and a shop banner using a button which appears the same.
Mac OS 10.6.8, Safari 5.1.7

Can you tell me, when you click the "edit" button to upload an avatar image, do you get the file browser prompt, and then after selecting a file nothing happens (e.g. you never see the selected file appear as your avatar), or does clicking the "edit" button not invoke the system file browser at all?

This didn't make it into this past weeks release but hopefully it will be fixed this week. It seems to be an issue only with older versions of Safari. You could try updating your avatar in Chrome or Firefox until we're able to get this fixed. Sorry again for the inconvenience!
